Abstract

Various stable N-fluoropyridinium salts with a non-or weakly nucleophilic counter anion such as TfO−, FSO 3−, BF 4−, SbF 6−, ClO 4−, CH 3 SO 3− etc., or with an electron-donating or-withdrawing substituent (s) on the pyridine ring were synthesized and their properties investigated. N-Fluoropyridinium-2-sulfonates, N-fluoroquinolinium triflate, and highly hindered N-fluoro-2, 6-di-t-butylpyridinium salts were also synthesized. They were ...
